How can I add LDFLAGS for bsp build?

Hi Dave & Joel:
Thanks for your replies.
I'm building RTEMS bsp, I think it should not find libm.so or lib.la in
LD_LIBRARY_PATH in configure script of RTEMS (5.1),
In fact, the compiling has -lm added, but still missing floor references:
arm-rtems5-gcc -march=armv7-r -mthumb -mbig-endian -mfpu=vfpv3-d16
-mfloat-abi=hard -Og -ggdb -ffunction-sections -fdata-sections -Wall

-Wnested-externs -B./../../lib/libbsp/arm/tms570

undefined reference to `floor'
I added LIBS=-lm in bsps/arm/tms570/config/tms570lc4357.inc (which is I
added for a new BSP), it passed build bsp,
however, in application build, I'm building application with waf, but ./waf
configure did not pass "test c program", due to the link flags for
application still has no -lm, which reported again undefined reference to
floor
following is config.log
